1. California schools’ absenteeism data:
Chronic absenteeism rate is “The unduplicated count of students determined to be chronically absent (Chronic Absenteeism Count) divided by the Chronic Absenteeism Enrollment at the selected entity for the selected population using the available filters.”
The graphics presented here use the chronic absenteeism rate of the total students of each academic institution and average it by county to create the visualizations. This project uses data of chronic absenteeism from California Department of Education of the year 2021-2022, that is publicly available here: https://www.cde.ca.gov/ds/ad/filesabd.asp.
2. Outdoor air pollution by county in California:
Particulate matter is deemed as a cause for respiratory illnesses in both children and adults. Particles of less than 2.5 μg/ m3 (respirable) can infiltrate the gas-exchange region of the lungs. PM 2.5 has been related to health effects like reduced lung function, asthma and other pulmonary diseases in children and adults who were exposed to high levels of endotoxins present in PM (Morakinyo et al., 2016) .
Average daily outdoor PM 2.5 air pollution by county in California is available as one of the county health rankings of the state here: https://www.countyhealthrankings.org/explore-health-rankings/california/data-and-resources.
